Implement a system which uses encryption of the query string, with site owners given access to the decryption key
I like this idea a lot. First, it assumes that data privacy is the real issue, as Google publicly said it is. If that really is the case, then Google has a responsibility to find a solution that doesn't eat 10% of the keyword data and this proposal sounds like a start.
However, I still don't feel we've had a clear enough explanation of the problem that needs to be solved by hiding keyword data. Without that, it's pretty hard to know if any alternative really addresses the problem that Google has been working on here since at least last year.
